AUGUST BECKER, OF NEW YORK, N. Y.

MACHINE FOR TRANSFERRING GLUE TO-PAPER.

SPECIFICATION forming part of Letters Patent No. 498,502, dated May 30,1893.

Application filed January 6, 1893- Serial No. 457.560- (No modelii Toall whom it may concern:

Be it known that I, AUGUST BECKER, acitizen of the United States,residing in New York same; and the invention consists of an apparatusfor transferring glue to sheets of paper and other articles, whichcomprises a vessel for receiving the adhesive substance, aspringactuated roller supported in removable bearings of saidvessel, abelt attached to said roller, and adapted to be drawn over a horizontaltable, said belt being attached at one end to the roller and provided atthe opposite end with a handle and aretaining device by which it can beattached to the outermost end of the table and a hinged cover for saidvessel, which cover is provided with a regulating device so as to act inthe nature of a doctor.

The invention consists further, in the construction and combination ofparts and details, which will be fully described hereinafter and finallypointed out in the claims.

In the accompanying drawings, Figure 1, represents a plan-view of myimproved apparatus for transferring glue to sheets of paper or othermaterial. Fig. 2, is a vertical longitudinal section of the same on line2, 2, Fig. 1, and Fig. 3, is a vertical transverse section on line 3, 3,Fig. 2, being drawn on a somewhat smaller scale.

Similar letters of reference indicate corresponding parts.

Referring to the drawings A represents a receptacle or vessel for liquidI glue or other adhesive substances. The vessel A is preferably made ofsheet metal and provided with a Water-bath B below the same so as tokeep the glue or other adhesive material liquid during the use of theapparatus. The vessel A is preferably made of oblong shape and providedat both sides with journaled bearend is attached to the roller itself,so that Y When the roller is turned on its axisin one direction, thespring is set to tension, while when the roller is released, it isturnedby the spring in opposite direction and returned to its initialposition. A belt D is attached to the surface of the roller, said beltbeing made of leather, thin sheet metal or other suitable material, theopposite free end of the belt or apron being provided with'a handle dand a hook-shaped retaining device d which engages the outermost end ofa horizontal table E which is supported at one end by thevessel Acontaining the adhesive substance and at the opposite end by means ofbrackets, legs or other suitable supports F asshown clearly in Fig. 2.When the retaining device (1 is. released from the outermost end of thetable E, the tension of the spring of the roller 0 winds the belt orapron around the roller until the handle at arrives at the hinged coverA of the vessel A, the handle d preventing the further drawing in of theapron into the vessel A. The hinged cover A'is provided with a curvedarm a that is hinged to the outer end of the cover A" and threaded atits opposite end, the threaded end being engaged by a screw-nut a whichby means of a groove is engaged by the forked end of the stay A so thatwhen the screw-nut is turned in one direction, the cover is pressed withmore or less pressure on the belt as the sameis drawn over the inneredge of the table E, while when the belt to the surface of the sheet.

paper, cloth, leather or other sheet to which the adhesive substance isto be transferred is placed on the apron and then removed from the same,by which operation a coating or film of adhesive substance istransferred from The end of the apron D is then released from the table,so that the tension of the roller draws in the belt and supplies a newcoating of adhesive substance to the same. Then the apron is againstretched over the table, retained in position and the glue of the sametransferred to the next sheet and so on. The water-bath s heated by alamp or other source of heat, so that the adhesive substance is retainedin liquid state in the vessel A. When all the glue has been transferredby the apron to the sheets to be pasted on the articles to be covered, anew supply of glue is placed into the receptacle A. This is accomplishedby removing the nut a from the stay A and moving the cover on its hingedconnectionin open position,so that access is thereby given to theinterior of the vessel. When it is desired to clean the vessel, theroller is removed with its bearings from the vessel A, so that therebythe vessel, the roller and the belt can be readily cleaned and thenreplaced into the vessel A, whereupon the cover is returned to positionand the operation of transferring the adhesive substance continued asbefore described. Any glue which is transferred by the surface of theroller 0 to the under side of the belt D is transferred to the inneredge of the table E at the time when the apron is moved over the table,so that but little glue adheres to the under side of the apron tointerfere with the proper working of the apparatus.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- 1. The combination,with a vessel for adhesive substances, of a spring roller journaled insaid vessel, a belt or apron attached to said roller, said belt beingprovided with a handle and a retaining device at the outer end, ahorizontal table extending partly over the vessel, a hinged cover forsaid vessel, and means for pressing the hinged cover with more or lesspressure on the belt or apron so as to regulate the supply of adhesivesubstance to the surface of the apron, substantially as set forth.

* 2. The combination, with a vessel for adhesive substances, providedwith removable journaled bearings, a spring roller supported in saidbearings, a horizontal table extending partly over the vessel, a belt orapron attached to the roller, said belt being provided at the outer endwith a suitable retaining device for engaging the outer end of thetable, a hinged cover extending over the apron and means for regulatingthe pressure of the cover on said apron, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

AUGUST BECKER.
